Panix.com has a feature that sidesteps that problem. It accepts any email address that looks like: hackernews@myname.users.panix.com, where you can customize "hackernews" to be a mailing list, company, or any text; and "myname" is your actual email address, eg myname@panix.com. No charge. Works great. Easily filtered. Disclaimer: just a satisfied customer.
